John P Holdren is now President Obama's Science Adviser or "Science Czar"

The following is from a book Holdren co-wrote in 1977, "Eco Science" with Paul R Ehrlich and Anne H. Ehrlich:

(page 575 "Direct Assaults on Well-Being")

Fluorides

Fluoridation of public water supplies for partial protection against tooth decay is an emotion-charged subject. The scientific evidence supporting the efficacy and safety of mass fluoridation at the generally recommended level of 1 milligram per liter of water (1 ppm) is not as good as it ought to be, but neither is there convincing evidence that it is harmful. although there are certainly some cranks in the antifluoridation school, there are also some serious and competent scientists and responsible laymen who have been unmercifully abused because of the position they have taken on this controversial issue. Perhaps the strongest argument against mass fluoridation of drinking water is that individual treatment with fluoride is simple and can be supplied cheaply on public funds for those wishing to use it.

There is no question that fluoride is toxic in high concentrations, and fluoride pollution from a variety of industrial activities is a significant problem. Fluorides are discharged into the air from steel, aluminum, phosphate, pottery, glass, and brick works. These sources together emit perhaps 150,000 tons of hydrogen fluoride annually, and the same activities emit some tens of thousands of tons of fluorides annually into waterways. Intentional addition of fluorides in fluoridation programs makes a modest but not negligible contribution of perhaps 20,000 tons per year to the human-caused fluoride inputs to the environment.

The main problems encountered in trying to evaluate health threats from fluoride pollution are familiar ones: the boundary between safe and unsafe levels is a fuzzy one; some individuals are more sensitive than others; and fluorides may act in combination with other pollutants to do damage at concentrations where the fluorides alone would not be harmful.

Fluorides have been shown to concentrate in food chains, and evidence suggesting a potential for significant ecological effects is accumulating. Harm to terrestrial plants and algae at concentrations encountered in polluted environments has been documented, and the ability of certain plants and microorganisms to synthesize particularly toxic organic fluorides has been demonstrated. The toxicity of inorganic and organic fluorides to soil organisms is essentially unexplored and is a potential danger point.

Children in America are dying from untreated tooth decay. And dentists are resisting any change that might alleviate the problem. Sixty-six percent of Medicaid eligible children (12.6 million) are not receiving any dental care. And the number of dentists has gone down in recent years and the number of dentist-shortage areas has gone up.

At least 50 percent of the average dentist's income now comes from elective cosmetic procedures. If dentists spent less time giving wealthier Americans artificially whitened grins, they would have more time to treat the serious oral disease that plagues millions of poorer Americans.

In 2000, the US Surgeon General revealed the ugly truth - that the low-incomed and minorities aren't getting the dental care wealthier Americans take for granted.

Many reports, meetings, symposiums, studies, conferences and years later, nothing has changed. Representative Dennis Kucinich held his fourth hearing on this issue on October 9, 2009 as chairman of the Domestic policy Subcommittee of the Oversight and Government Reform Committee.

In his opening statement, Kucinich said:

"On February 25, 2007 Deamonte Driver, a twelve-year-old boy from Prince George's County, Maryland died from a brain infection caused by untreated tooth decay. Deamonte's tragic death could have been easily prevented by access to dental care - dental care he was entitled to.”

About two dozen dentists contacted refused to treat Deamonte Driver because he was on Medicaid.

"At our first hearing in May 2007, we learned that Deamonte Driver was not the only Maryland youth who wasn't receiving dental care to which he was entitled by Medicaid, said Kucinich. His investigation found that approximately 11,000 Maryland children on Medicaid had not seen a dentist in at least four years.

Representative Elijah Cummings, a member of the committee, said he grew up without dental care and believed his constant tooth decay pain was normal. He doesn't want any kids to have to endure that, especially when it's easily treated, he said.

Cummings said he has lots of kids from fluoridated Baltimore going to the University of Maryland for dental care, partially because of Deamonte Driver's death because "I want them to grow up," he said. Many of them have such bad tooth infections that traveled to and infected their eyes - which happens before the infections reaches the brain which killed Deamonte Driver, said Cummings.

Kucinich said, “A GAO report (2007), the first of its kind since 2000, revealed that millions of Medicaid-enrolled children suffer from tooth decay - almost one-third of the total Medicaid population. Medicaid children are roughly twice as likely as privately-insured chidren to suffer from tooth decay. Moreover, this pattern has persisted for years; very little had been done to improve access to and utilization of dental services. In a sense, the problem of tooth decay is getting worse because the rate of decay in the teeth of children aged two through five has increased in recent years."

Today, there are millions of children just like Deamonte Driver - entitled to dental care but not getting it, said Kucinich

The use of fluorine compounds in various areas of medicine, particularly in dentistry, as well as in agriculture and industry became very popular in the second half of the 20th century.

Fluorine owed this widespread acceptance to observations that its compounds stimulate ossification processes and reduce the prevalence of caries. Unfortunately, growing expectations overshadowed the truth regarding interactions of fluoride on the molecular level.

The fact was often ignored that fluoride is toxic, even though laboratory data stood for a careful approach to the benefits of usage. Excessive exposure to fluoride may lead to acute poisoning, hyperemia, cerebral edema, and degeneration of the liver and kidneys. Acute intoxication through the airways produces coughing, choking, and chills, followed by fever and pulmonary edema. Concentrated solutions of fluorine compounds produce difficult to heal necrotic lesions.

In spite of these dramatic symptoms, acute intoxications are relatively rare; the more common finding is chronic intoxication attributable to the universal presence of fluorine compounds in the environment.

The first noticeable signs of excessive exposure to fluoride in contaminated water, air, and food products include discolorations of the enamel. Dental fluorosis during tooth growth and loss of dentition in adulthood are two consequences of chronic intoxication with fluorine compounds. Abnormalities in mineralization processes affect by and large the osteoarticular system and are associated with changes in the density and structure of the bone presenting as irregular mineralization of the osteoid.

Fluorine compounds also act on the organic part of supporting tissues, including collagen and other proteins, and on cells of the connective tissue. These interactions reduce the content of collagen proteins, modify the structure and regularity of collagen fibers, and induce mineralization of collagen.

Growing deformations of the skeleton reduce mobility and result in permanent crippling of the patient. Fluoride increases the mass of non-collagen proteins such as proteoglycans and glucosaminoglycans, accelerating skin aging even though protein biosynthesis is generally suppressed. The final outcome includes progressive vascular lesions and disorders of energy metabolism in muscles.

In conclusions, the use of fluoride, particularly by dentists and pediatricians, must be controlled and adapted to individual needs. It is worth remembering that fluoride: is the cause of disability due to bone deformations and abnormalities in the musculoskeletal system; reduces the incidence of caries but do not protect against tooth loss; exerts an adverse effect of metabolic processes in the skin; accelerates calcification of vessels and thus reduces their elasticity; inhibits bioenergetic reactions, in particular oxidative phosphorylation, reducing physical activity of muscles. These findings suggest that fluorine may be yet another factor in accelerated aging and revive the dispute started more than two and half thousand years ago whether aging is a physiologic or pathologic process. The understanding of factors modifying the process of aging is the basis for preventive measures aimed at extending life and maintaining full psychosocial activity.

June 18, 2009 -- It has now been over three years since Professor Chester Douglass of the Harvard Dental School trashed Bassin's (his own student!)[published and peer-reviewed] study associating fluoride exposure to osteosarcoma [bone cancer], with the promise that his paper (to be co-authored by Robert Hoover and Gary Whitford) - to be published in the Summer of 2006 - would refute her findings. We've been waiting and waiting, but still no paper has appeared. Meanwhile, proponents of fluoridation such as

1) Dr. Peter Cooney, chief dental officer of Canada 2) the Australian National Health and Medical Research Council (NHMRC, 2007) and 3) the South Central Strategic Health Authority in the UK,

continue to cite Douglass' letter as if it were a fully fledged research article scientifically rebutting Bassin's findings. So much for authorities who insist upon "peer-reviewed and published" science!

For those new to the Chester Douglass scandal, here is a short time line.

1977. In the wake of the furor generated over the research by Drs. Dean Burke and John Yiamiouyannis showing cancer rates had increased in 10 American cities after fluoridation had begun in the 1950's, the US Congress ordered the National Toxicology Program (NTP) to do animal studies investigating a possible connection between fluoride and cancer.

1990. After a delay of 13 years the NTP finally reported back on the animal-cancer study. They found a number of cancers - all but the osteosarcomas were subjectively downgraded by a government review body, much to the disgust of Dr. William Marcus, who was the chief toxicologist for EPA's Office of Drinking Water. Marcus was fired by the EPA for being too noisy about the matter. Even so, the finding of a dose related increase in osteosarcomas in the male rats, created quite a stir in the media and in dental circles.

1991. Very quickly an article was published in the Journal of the American Dental Association (JADA) co-authored by Douglass. In this study by McGuire et al., the authors reported that they had found no evidence of an association between fluoridation and osteosarcoma and even suggested the opposite: that fluoridation was actually protective against osteosarcoma. This article was given lavish treatment by JADA. The beautiful cover, featuring a huge glass of water with a lake and mountain in the background, carried the statement: "Fluoride and Cancer. Study points to protection."

McGuire et al. made it clear in the text of this article that a positive finding of a relationship between fluoridation with osteosarcoma would have serious consequences for the fluoridation program, a possibility they were clearly worried about, as the following quotes make clear:

"An incorrect inference implicating systemic fluoride carcinogenicity and its removal from our water systems would be detrimental to the oral health of most Americans, particularly those who cannot afford to pay for increasingly expensive restorative dental care" (p.39)

"Because of its strengthening action, fluoride has been widely accepted as the responsible agent for the dramatic declines in the tooth decay rates of U.S. children and adolescents." ( pp.39-40)

"A disruption in the delivery of fluoride through municipal water systems would increase decay rates over time." (p.40) (The authors cited the dubious Antigo study to support this claim, PC)

"Linking of fluoride ingestion and cancer initiation could result in a large-scale defluoridation of municipal water systems under the Delaney clause." (p.40)

The authors concluded, based on this small study, that there was no relationship between fluoridation and osteosarcoma, and even suggested that:

"fluoridation at recommended levels may provide a protective effect against the formation of osteosarcoma" (p.44)

This allowed Douglass and his co-authors to reach the final conclusion that they clearly wanted out of this study:

"Given present knowledge, every effort should be made to continue the practice of fluoridating community water supplies." (p. 45)

1992. The NIEHS chose Chester Douglass to undertake further research to investigate the possible relationship between fluoridation and osteosarcoma. It is incredible, that such a sensitive research effort should have been given to a dental professor, let alone one who had clearly articulated how serious it would be for the fluoridation program should a positive finding be found.

Over the next 10 years (or more), this funding from NIEHS kept on being renewed, despite the fact that, apart from one abstract, Douglass had published nothing on this research. A total of over a million dollars flowed into Douglass' Harvard coffers for this work. These are really patient people at NIEHS!

2001. Then in 2001, Elise Bassin (Douglass' graduate student) successfully defended her PhD thesis. In this, she reported, in what she herself called a robust study, that young boys exposed to fluoridated water in their 6th, 7th and 8th years had a 5-7 fold increased risk of succumbing to osteosarcoma by the age of 20.

2002. In a presentation that Douglass gave to the British Fluoridation Society (BFS), he assured the members of the BFS that his work had found no linkage between fluoridation and osteosarcoma. He somehow failed to mention that his graduate student had found the very opposite to be the case. The BFS reported Douglass' claim in their pamphlet, and used it in their continued promotion of fluoridation. There was no mention of Bassin. The BFS pamphlet went unchanged, long after the existence of Bassin's study had been revealed.

2004. Douglass sent a letter to the National Research Council (NRC) fluoride review panel talking about his research (NRC, 2006). Again he claimed that his work had found no relationship between fluoridation and osteosarcoma. Again he made no mention of Bassin's work, but this time he gave her thesis as a footnote. Any casual reader would have reasonably assumed that Bassin's thesis supported Douglass' claim. Douglass sent a similar letter to his funders at NIH.

2005. In January, acting on a tip-off from Myron Coplan, Michael Connett visited one of the libraries at Harvard and located Bassin's thesis in the rare books section. He was able to photocopy the chapter dealing with osteosarcoma. FAN sent this chapter both to the NRC review panel and to the Environmental Working Group (EWG) in Washington, DC. EWG called for an NIH enquiry into Douglass' behavior and released the story to the media claiming that Douglass was covering-up this important finding. They also mentioned that Douglass was a consultant for Colgate (he edited their monthly bulletin, "Colgate Oral Care Report'). This triggered wide coverage in the media including an important article in the Wall Street Journal (Begley 2005). However, the NIEHS meekly handed over the investigation to Harvard.

2006. One year later, Harvard exonerated Douglass of "deliberately" covering-up Bassin's work. A video clip from Fox News showing Douglass holding up the Harvard "get out of jail free" card, can be accessed at http://www.youtube.com/watch?v=5xR47jUqX9g&feature=channel_page

In March, the National Research Council fluoride report was released and stated:

"A relatively large hospital-based case-control study of osteosarcoma and fluoride exposure is under way (Douglass 2004) and is expected to be reported in the summer of 2006 (C. Douglass, Harvard School of Dental Medicine, personal communication, January 3, 2006)."Ref: http://www.nap.edu/openbook.php?isbn=030910128X&page=329

In May, Bassin, with three other Harvard researchers, published her findings in the Journal Cancer Causes and Control (Bassin et al., 2006). In the same issue, the editors published Douglass' effort to discount Bassin's findings and his promise that his "larger" study would show that Bassin's thesis didn't hold (Douglass & Joshipura, 2006).

The summer of 2006 comes and goes. No published paper from Douglass.

2007. The summer of 2007 comes and goes. Still no published paper from Douglass.

2008. The summer of 2008 comes and goes. Still no published paper from Douglass.

2009. June 18. The first day of summer is just three days away and still no published paper from Douglass.

Meanwhile, those who have examined Douglass' proposed methodology have concluded that there is no way that it can actually disprove Bassin's thesis because the measure of exposure they are using is bone fluoride levels - and there is no way that this can test Bassin's thesis since this is based on which year the young boys are exposed to fluoride. The bone level will only give the cumulative exposure after 20 years . Moreover, another extraordinary weakness of this matched case and control study, is that the controls are young men with other forms of bone cancer (other than osteosarcoma). Clearly, if fluoride was to also cause any these cancers - as it well might - that would completely eliminate any significance of this study!

With such huge weaknesses to this study it is quite conceivable that no reputable journal will touch it. So standby for another cover issue of JADA!

Meanwhile, some believe that Douglass was a "stooge" in all this, and that the person really pulling the strings was Dr. Robert Hoover at the National Cancer Institute. It was Hoover who had done battle with Burke and Yiamiouyiannis in the 1970s. It was also Hoover who conveniently found a reason to discount his own findings of an increase in osteosarcoma in young men living in fluoridated counties covered by the SEER registry (Hoover et al., 1991). Hoover was also the co-author of the paper delivered by Douglass to the BFS in 2002. Hoover was aware of Bassin's findings but apparently went along with Douglass in not revealing them in this paper. Moreover, Hoover has been a part of the Douglass study from the very beginning. Currently, he is listed as the Principle Investigator of the Douglass study, and the current funding appears to all be coming directly from "intramural" funding at NCI. NIEHS funding ran out several years ago.

Most dentists neglect low-income Americans all year, except for one “Give-Kids-A-Smile” day, filled with media events, feel-good stories,corporate sponsorship, costly T-shirts, but little drilling and filling. When the media spotlight goes out, so do the dentists. At the same time, organized dentistry fights hard against any viable group willing to alleviate the US dental health epidemic year-round.

Theoretically, government sponsored dental care, under Medicaid, is free for children living in poverty. Sadly, “nationally, only about 10% of all dentists accept Medicaid patients,” according to a report by the Children’s Defense Fund. And over 108 million Americans lack dental insurance, according to the American Dental Association (ADA).

According to American Family Physician, more than three out of four dentists do not treat the uninsured.

Dentists’ income is derived mostly from private insurance and patient’s pockets, says the ADA. Dentists aren’t hurting. Rated among the highest-paying jobs by bizjounrnals.com, the top ten money-making cities for dentists range from Charlotte ($195,540) to Omaha ($176,830).

Meanwhile, 6.5 million children aged 2 through 18 in Medicaid have untreated tooth decay, according to the Government Accounting Office, often forcing them to get expensive hospital emergency care when the decay spreads, the pain is unbearable, costing the taxpayers thousands of dollars to treat. Some have died from untreated tooth decay.

The logical solution is to require dentists to treat more low-income Americans – either for free, for what Medicaid offers, or on a sliding scale. But dentists don't like mandates – well for themselves anyway. They do like fluoridation mandates, though. Dentists prefer to treat the water rather than the individual.

Dentists didn’t make it on their own. Government subsidizes dental tuition and dental schools and regulates their licenses. Dentists need to give back or allow other viable groups to fill the void.

Dental Health Aide Therapists are currently repairing and pulling teeth in rural Alaska where no dentist would live or work. The American Dental Association and the Alaska Dental Society spent $1 million on a lawsuit trying unsuccessfully to stop them.

Organized dentistry now lobbies against solo-practicing dental hygienists, denturists (false teeth makers) from working directly with the public and Dental Therapists in any other state.

Organized dentistry uses its credentials, political clout and deep pockets filled up with corporate cash to lobby our legislators to pass laws that benefit themselves while an oral health epidemic occurs on their watch. See: http://tinyurl.com/PoliticalClout

Unfortunately, organized dentistry uses GKAS day to convince legislators to give them more money to treat Medicaid patients and to promote water fluoridation - a tax-wasting scientfically failed method of reducing tooth decay.

Although the District of Columbia is 100% fluoridated and has the nation’s highest density of dentists, 44% of children in a typical elementary school have cavities in primary teeth – 34% is unfilled. Just 30 dentists (2.5 percent) are Medicaid billing dentists with at least one paid claim, according to “Issue Brief: Oral Health Is Critical to the School Readiness of Children in Washington, DC.”

The Raleigh News & Observer reports, that the ability of patients to pay and the lack of dentists have negatively affected access to dental care and the problem likely will get worse in North Carolina, which is 88% fluoridated About 200 emergency department dental cases occur daily throughout the state, they report.

“Nearly half of [60% fluoridated] Massachusetts children experience tooth decay before third grade…’We struggled over the last several years, particularly in part of the district I represent, which is Cape Cod, to even get any dentists to accept Medicaid patients,’" reports the State House News Service on February 2000.

Rochester, NY, is fluoridated: "Hundreds of local children are ending up in the operation room because of cavities that could have been prevented...The Eastman Dental Center sees more than 300 of these kinds of cases a year. In [fluoridated] Buffalo, 700 plus cases, and thousands state wide [NYS is 73% fluoridated],” according to NBC News

Although Kentucky is 99.8% fluoridated, “Last year, four area hospitals had 1,500 visits from patients seeking help with tooth pain…About a third of those cases involved children and teens, reported the Messenger-Inquirer on March 8, 2008 .

“State officials have found that 4,500 Kentucky 3-year-olds have dental pain each day, McKee said. Nearly half of preschoolers have untreated tooth decay,” they report.

Minnesota is 98% fluoridated: "Last year, there were 22,000 emergency-room visits for dental problems." reported the Star Tribune on January 22, 2009.

In West Virginia, 92% fluoridated, "It's especially difficult to find an oral surgeon who accepts Medicaid patients in Southern West Virginia where dental health problems are rampant,” reports the Charleston Gazette on January 11, 2009.

New York State Department of Health statistics illustrate fluoridation’s inability to equalize cavity rates between low and high socio-economic-status groups, and that fluoridation and tooth decay rates are not inversely related See chart: http://www.freewebs.com/fluoridation/chart.htm

What is needed is to train Dental Therapists in this country. The ones working in Alaska were trained for two or three years in New Zealand. They drill, fill and pull teeth as effectively as dentists and have been working for decades in developed countries. As a result, children in New Zealand have no unfilled cavities because they are seen in school by Dental Therapists every year and rural Alaskans aren't pulling their own teeth. Organized dentistry is at odds with public health dentists on this. The former doesn't like any groups infringing upon its lucrative monopoly - even if it means Americans must suffer from dental neglect 364 days a year.

Sixty-four years ago, on January 25, sodium fluoride was slowly poured into Grand Rapids, Michigan’s public water supply to prove that fluoridation reduces children’s tooth decay. Five years into the experiment, things weren’t going as expected. Cavities declined equally in the non-fluoridated control city of Muskegon, too. So to blur the truth or prove their expectation, Muskegon was fluoridated also.

For example, according to data presented at the 2006 American Association for Dental Research’s annual meeting:

-- Researchers following children from birth found almost twice the amount of dental fluorosis in children drinking fluoridated water but no less decay than children drinking non-fluoridated water. (1)

-- No significant relationship was found between fluoride exposure and cavities in permanent teeth of 6 to 9-year-old's in Campeche, Mexico(2). Previously, it was reported that 56% of this group has dental fluorosis.(3)

-- A U.S. national study reports cavity prevalence increased by 15% in 2 to 5-year-olds, in surveys taken between 1988-1994 and 1999-2002,(4) The Centers for Disease Control report that 1/3 to 1/2 of U.S. schoolchildren display dental fluorosis.(4a)

-- Breastfed US children have less cavities than non-breastfed.(5) even though breast milk has 250 times less fluoride than dentists claim is optimal to reduce cavities. Breastfeeding is also protective against fluorosis.(5a)

-- Although New York City fluoridated in 1965, NYC children of Chinese descent suffer a much higher prevalence and severity of tooth decay than the national average (63% vs 38%). (6)

-- About half of 7 to14-year-old children from fluoridated Rochester, NY, have cavities. Latino children had significantly higher caries experience than African-American and Caucasian children, thus indicating that disparities exist among different ethnic groups even when the water is fluoridated.(7)

Grand Rapids children are showing high rates of tooth decay and dental fluorosis. According to the Grand Rapids Press, one pediatric dentist said in 2007 “…we see children under the age of 2 with active decay…Rather than just a few cavities, we're seeing a lot of cavities. It's not unusual to see a child with 8 to 10 cavities."

Detroit Michigan is also fluoridated.

A study shows that, although fluoridated tap water is the most consumed item, 83% of low-income Detroit African-American adults, 14-years-old and over, have severe tooth decay. Almost all Detroit’s African-American 5-year-olds have cavities, most of them go unfilled.

In fact, there are cavity crises in all fluoridated cities and states (See: http://www.FluorideNews.blogspot.com ) because 80% of dentists refuse Medicaid patients and over 108 million Americans lack dental insurance.

Our food supply has become fluoride-polluted. The USDA had to create a database of fluoride content of some foods to help Americans tally their daily fluoride intake to avoid dental fluorosis and the National Institutes of Health just granted $3 million to a researcher to find out why children are getting dental fluorosis.

It makes better fiscal sense to stop adding fluoride chemicals into the public water supply instead of feeding the research community millions of dollars to tell us we are over-fluoridating our children.

These studies add to a growing body of evidence pointing to fluoride's ineffectiveness and lack of safety: See: http://www.fluoridealert.org/health/teeth/caries/fluoridation.html#top
